[ 1/1 Equation]
Work: Find the solution of equation 9.4056x2+18.81x-152.17 = 0 .
Question type: Equation
Solution:Original question:
11757 1250 | x | × | 2 | + | 1881 100 | x | − | 15217 100 | = | 0 |
| Left side of the equation = | 11757 625 | x | + | 1881 100 | x | − | 15217 100 |
| = | 94053 2500 | x | − | 15217 100 |
94053 2500 | x | − | 15217 100 | = | 0 |
Transposition :
94053 2500 | x | = | 0 | + | 15217 100 |
Combine the items on the right of the equation:
94053 2500 | x | = | 15217 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 15217 100 | ÷ | 94053 2500 |
| = | 15217 100 | × | 2500 94053 |
| = | 15217 | × | 25 94053 |
We obtained :
| x | = | 380425 94053 |
Convert the result to decimal form :
| x | = | 4.044794 |
